Metamorphic rock is a type of rock that the preexisting rock becomes a new rock.
Metamorphism has also different types; the Contact metamorphism and the regional metamorphism. Contact metamorphism happens when magma is mixed with the solid rocks in the surroundings. For example when magma is starting to form igneous rock, it may increase that probability that it will reach the country’s rock and that’s affected the current formation of the rock. Regional metamorphism is also called as dynamic metamorphism. This happens when the pressure from underground makes the rock from above move and change into new rock formation
Clastic because clastic sedimentary rocks are made up of pieces of pre existing rocks
Pre-existing rocks, or protoliths, become metamorphic rocks through a process called metamorphism, which involves heat, pressure, and sometimes chemical reactions. This can occur through contact or regional metamorphism, leading to various new rock types depending on the original rock and environmental conditions. Notable examples include limestone becoming marble and shale transforming into slate.
